JLU Vibration highway speeds

[FreeindeedMikeD]

I have a 2020 JLU that has developed a subtle vibration from around 65 mph and up. It started while I had the stock Bridgestone's on it. I Upgraded to a new set of Rubicon take-offs and the issue is still there. Tires are balanced, nothing can be felt in the steering wheel. Jeep is not yet lifted. From the research I have done on here, it would seem that this is a driveshaft issue. Can anyone give me their opinion if this appears to be a driveshaft issue. If so, what do i look for and how can I correct it? Thank.

Your front driveshaft isn't spinning in 2WD so if it was driveshaft vibration it would have to be coming from the rear. Have you checked the torque on your suspension connections?

No I have not. What areas of the suspension should I check?

Check the front driveshaft in 2wd. It shouldn’t spin, but if there is a FAD issue it could be.
